To all whom it may 0mm.-

Be it knowntha't I, VIc'ron M. ALLEN, a citizen of the United States, and a resident of lVaverl in the county of Tioga and State of ew York, have invented certain new and useful Improvements in Ventilating VVindow-Shades. of which the following is a specification. This invention relates to ventilating window shades and has for its object to provide a shade of this kind 'vhich is simple in construction,- may be easily applied to a window frame may be readily adjusted to admit or exclude light or sunshine, and which'will automatically adjust-itself in a wind so as not to be torn or displaced.

Another object is to provide a series of horizontal panels which may be operated in unison and simultaneously adjusted to any desired angle so as to admit light-and air and exclude sunshine and the view of those within from the outside. The panels may. however, be quickly adjusted to permit those insideto look out when desired and to admit sunshine. a

A further object is to provide means for protecting the shade from dust--and the sun when not in use, saidprotecting means being capable of housingt-he shaft in compact.- form and permitting it tobe quickly withdrawn for use when occasion requires. f

Other ohjectswill appear as the description proceeds.- F The invention will he first hereinafter described in connection with the accompan ing drawings, which constitute part of this speciticatioIL-and then more specifically defined in the claims at. the end ofthe descrip- In-the accompanying drawings, wherein similar reference characters are; used to designate corresponding parts throughout the.

frame and shade supporting frame; showing the weighted disk to which the panels are connected for adjusting them to difierent angles and which is adapted to yield in the wind to prevent the shade from being torn or displaced.

Fig. 4 is a detailed view of said weighted disk looking at the other face thereof.

Fig. 5 is a sectional view of the weighted disk in association with its supporting I bracket and the pin onthe 'panel bow-which is designed to engage any one of a seriesof sockets inthe face of the wheel. r

Fig. 6 is an end view of the. casing-for housing the shade when rolled up, showing l more particularly the door. or closure for said casing; and w Fi 7 is a longitudinal sectionthrougli one end of saidcasing and closure. f

The curtain comprises aplurality of horizontal panels -1-,-made of textile or other suitable material, and having their "inner edges connected at intervals :to vertical side strips 2 of similar '-ll'l{lt(.lltll,"0l19 of said strips being designed to extend along each side of a window frame 3, as indicated in Fig. 2 when'the shade is in uses The inner and outer edges of each panel are reinforced and held in position by horizontal spring wires or rods 4:, preferably run throughthe hems at said edges of said panels. The upper' panel is extended upwardly. asat 5'."a-nd attached to a shaft (5. arranged in av horizon tal tubular housing or casing 7-attachedto the upper-cdgeportion of a metal frame 8 over-which the shade works and whichmay be readily fastened to a window. frame by screws 9. Fig.2. engaging 'sl otsltl and 11 in said metalframe; Fig: 1'. V Y I a The lower portion of the casing? is 'open to permit -the shade tohe. wound u pin the same or'l'with drawn. thei' ,efro11i' 'as occasion requires. 'l his open .POIiLlOTlof thc casing is 1 normally: closed. however;.l'iy sia. 'door or 1 00 closure 12 which has end flanges iilla 'ntvo ver "the ends oi the casing; 'as'shownin Figs) 6 and 7. permitting said door or closureito-he swung iiponth-e casing as its axis for (2105- 7 ing or uncovering the: opengflower portion ofsaid casing. The door orclosure "12 depends for some distance h'el cw: th casin 7, and i norm all-y .itsllower edge 1 bears against the sh ado; asshownin Fig. 2. at holding i't havea crank l tprotru'ding.from one end of I a the casing for rolling up the shade.

The outer edges of the panels 1 are connected together by cords 15 attached to the corners thereof at intervals corresponding to the intervals between the inner edges of said panels on the strips 2. The outer edge of the top panel is connected to arms 16 depending from a rock shaft 17 extending across the frame 8. The free ends of said arms are bent inward at 18, Fig. 1, to detacha'bly engage the outer edge of said upper panel, so that the arms may be detached from the shade when the latter is to be-rolled up. By swinging the arms 16 on the rock shaft the upper panel may be adjusted to any desired an le, and owing to the cord connectionslii etween the several panels,

. all of said panels will be adjusted in unison so as to be arranged substantially parallel to one another.

To retain the panels in adjusted position, the arm 16 at one side of the shade is provided with-a pin 19 adapted to engage any' one of an arcuate series of sockets 20 in the face of a disk or wheel 21 which is also carried by .the rock shaft 17. Said disk or wheel 21 is weighted at 22 at the bottom in order to normally maintain the panels of I the shade at a set position, but if said panels are caught by the wind the disk will yield or rotate toqprevent the shade from being torn or displaced. The rock shaft may be journaled in a bracket 23 at one side of theframe 8 and in a lug 24 at the other side thereof, or mounted in any other suitable way.

The wireor rod which is run through the hem at the inner edge of the lowest panel has its ends extended beyond the ends of said panel and bent to forma bow with arms 25 corresponding in length to the. arms 16. The free ends of the arms'25 have spaced angularly extending pins or studs 26 and 27. The studs 26 at the extreme ends of the arms are designed to be engaged with eye lugs.

28 on the lower portion of the frame 8, Figs. 1 and 2, when the shade is in use, and the studs 27, are intended to be hooked over the lateral edges of the lowest panel, as shown in Fig. 2, for holding the bottom portion of the shade close to the frame 8. When the shade is to be rolled up in the casing 7, the studs 26 are disconnected from the eye lugs 28 on the frame, and after the shade has been rolled up, as shown in Fig. 1, the arms 25 will depend from the loweredge of the same and be supported thereby near the frame 8. a I

When used on an open window, the shade may bereadily adjusted with itspanels at an upwardly or downwardly inclined angle so as-to admit light and air but exclude sunshine and prevent view of persons inside by those outside. The panels may also be adjusted to admit sunshine and to permit the occupants ofthe room to see out, if desired.

Inasmuch as the wind has free passa through the shade between the panels, sald shade will not be blown about or displaced like an ordinary shade. When the shade is used on a closed window, its operation is the same, the only difference bein that air is not admitted with thelight. 5f course, the panels may be dropped to vertical overlap ing position whenever it is desired to darlien the room. It will be observed that the shade is mounted complete on the frame 8 and may be quickly attached to any window frame by simply inserting the necessary SCIEEWS 9 in the latter to engage the slots 10 an 11.

Having thus fully described my invention,

what I claim as new and desire to secure by Letters Patent of the United States, is-
